Document Summary
Aerobics center longitudinal study (blair et al. , 1995) Changes over time by age n=9,777 men aged 20-82 at baseline. Test: two maximal treadmill tests between 1970 and 1989: mean interval between treadmill tests was 4. 9 years, mean follow up after second test was 5. 1 years o. For each treadmill tests, participants grouped into quintiles based on treadmill time: quintile 1 (shortest treadmill time) classified as unfit, quintile 2-5 classified as fit o. The acl study: fitness, fatness and all-cause mortality. Lee et al. (1999) studied the relationship between fitness, fatness and all-cause mortality risk o n= 21,925; men aged 30-83. Body composition measured using hydrostatic weighing, skinfold thickness (lean - < 25th. %; normal 25th%- < 75th%; obese >75th% based on percentiles), or both. o. Physical fitness measured using time to exhaustion on maximal treadmill exercise test (unfit = lowest quintile) o. Average follow up period 8 years during this time n = 428 deaths.
